As the bankruptcy unfolds, the cathedral has received several offers for the property, which includes the glass cathedral, designed by architect Phillip Johnson, and a 234-foot prayer spire.

A real estate group has offered $46 million for the 40-acre site, as did Chapman University. Both bids would allow the church to lease back its core buildings with the possibility of purchasing the cathedral.

The cash proposal by the Catholic Church would allow creditors to be paid back in full before the end of the year and would preserve the cathedral's cemetery.

"We think it would be as quick as a resolution as possible," Martin said.

Orange Bishop Tod Brown has said that the diocese needs a worship space for the more than 1.2 million parishioners in the area and that the 3,000-seat cathedral is a less expensive alternative to building a new cathedral. The diocese has considered a project in Santa Ana that would cost at least $100 million.

In recent weeks, the Catholic Church has made it clear that an offer would be solidified. On Friday, the diocese submitted formal proposals to both the Crystal Cathedral board and the creditor's committee.

Marc Winthrop, an attorney for the cathedral, declined to comment Friday.

The diocese said it would work with the cathedral to find an "acceptable alternative worship space," possibly another Garden Grove diocese venue, upon expiration or early termination of its lease. It also would renovate portions of the cathedral to bring it in line with worship practices.

"It's in their hands at this point," said Steve Bohannon, a spokesman with the diocese.
